Inherent in the Olympus servers is the hardware connection between the ASPEED BMC and the CPU JTAG chain. To make the most of this connection for hardware-assisted debug and test purposes, a high-performance, secure JTAG Master function is needed within the BMC.Alan SguignaMicrosoft Project Olympus Schematics and Embedded JTAG Run-Controltag:typepad.com,2003:post-6a01348365b3a6970c01b8d2c3f78c970c2017-12-03T16:26:36-06:002017-12-03T16:26:36-06:00As part of the Open Compute Project, Microsoft Azure is leading the charge in providing the technical information needed to democratize the server industry. Recently, they put into the public domain the full schematics and board files for an Intel Xeon Scalable Processor (Skylake-EP) server design. Reviewing the schematics provides great insight into the hardware design implementation needed to support at-scale debug via embedded JTAG run-control.Alan SguignaThe MinnowBoard Chronicles Episode 27: Segfault on my AMD Ryzen 7 1700Xtag:typepad.com,2003:post-6a01348365b3a6970c01b7c92ebf01970b2017-10-29T17:54:32-05:002017-10-29T17:54:32-05:00Last week, I suspected that I might be seeing segmentation fault failures on my new AMD Ryzen 7 1700X computer. I dug into this some more this week, and learned a lot!Alan SguignaASSET exhibits at the AUTOTESTCON Conferencetag:typepad.com,2003:post-6a01348365b3a6970c01b7c9218302970b2017-09-19T07:38:10-05:002017-09-19T07:38:10-05:00I was up in Chicago last week, attending the IEEE-sponsored AUTOTESTCON conference. ASSET demonstrated our ScanWorks boundary-scan test support of the Teradyne High-Speed Subsystem (HSSub).Alan SguignaAdvanced support for Teradyne HSSub PXIe systemstag:typepad.com,2003:post-6a01348365b3a6970c01b7c91efae7970b2017-09-11T07:48:30-05:002017-09-11T07:48:30-05:00We announced today the extended integration of ScanWorks’ boundary-scan test capabilities with the Teradyne’s PXI Express-based High Speed Subsystem (HSSub). Come see a demo at Booth #101 at the AUTOTESTCON conference!Alan SguignaSecurity of BMC Operating Systemstag:typepad.com,2003:post-6a01348365b3a6970c01bb09ab412a970d2017-07-02T13:58:50-05:002017-07-02T13:58:50-05:00Given that they are network-accessible, BMCs present an attack surface. Which operating systems are hardened enough to be secure against malicious actors?Alan SguignaAt-speed SPI Flash/EEPROM Programming using FPGA and JTAG - Revisedtag:typepad.com,2003:post-6a01348365b3a6970c01bb09a7baa6970d2017-06-21T16:25:25-05:002017-08-22T10:38:41-05:00One of the greatest challenges for designers and manufacturing engineers today is how to cost-effectively program SPI Flash and EEPROM memory after the devices have been soldered down onto a printed circuit board. Firmware changes typically occur multiple times during the board design and bring-up process. Changes are also common...Michael JohnsonEmbedded Boundary Scan for Defense Systemstag:typepad.com,2003:post-6a01348365b3a6970c01b8d28ed40c970c2017-06-21T11:18:19-05:002017-06-21T11:18:19-05:00ASSET was recently awarded a multi-year contract for embedding boundary-scan test technology within a military system design. This meets a requirement of greater than 92% structural test diagnostic accuracy in-system, and will save millions of dollars over the lifespan of the system.Alan SguignaAt-Scale Testtag:typepad.com,2003:post-6a01348365b3a6970c01bb09965930970d2017-04-30T13:32:49-05:002017-04-30T13:32:49-05:00Now that At-Scale Debug (ASD) is becoming a de facto standard on Intel designs for the remote execution of CScripts, what other applications can take advantage of this technology?Alan SguignaASSET and CCI collaborate on integrated test solutionstag:typepad.com,2003:post-6a01348365b3a6970c01b7c8cabb54970b2017-01-17T20:10:13-06:002017-01-18T20:50:28-06:00Combining boundary-scan structural test with functional test is a “best practice” approach to high test coverage at least cost. So, it only makes sense that ASSET collaborates with Circuit Check.Alan Sguigna
